SPECIFICATION forming part of Letters Patent N 0. 636,555, datedNovember 7, 1899.

7 Application filed August 9, 1899. Serial No. 726,627. (No model.)

To aZZ whom it may concern: v

Be it known that I, EMMET PROBST, a citizen of the United States,residing in Paterson, in the county of Passaic and State of New J ersey,have invented a certain new and useful Improvement in Shutter-Workers;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which itappertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

This invention relates to shutter-workers; and its object is to providea device of this nature which sh all be simple and inexpensive inconstruction and whereby the blind or shutter may be positively andquickly secured in any desired position from the inside of the apartmentwithout raising the sash or moving any other similar part.

The invention consists in the improved shutter-worker adapted foroperating the shutter or blind from the inside and in the combinationand arrangement of its various parts, substantially as will behereinafter pointed out, and finally embodied in the clauses of theclaim.

My invention is fully illustrated in the accompanying drawings, whereincorresponding letters of reference indicate like parts,

, The inner end of the shaft is bifurcated and and wherein- Figure l isan outside View of'a portion of a window casing and blind and theoutside end of my improved shutter-worker operatively disposed in theformer and connected to the latter. Fig. 2 is a vertical sectional viewof the casing, showing my improved shutter-Worker in position, certainparts of the device being also shown in section. Fig. 3 is an enlargeddetail view of that portion of the mechanism of my device constitutingthe locking means. Fig. 4 is a side View of that portion of my devicewhich is shown in Fig. 3, certain parts being represented in section;and Fig. 5 is a View similar to Fig. 4, illustrating a certainmodification of what is shown in said Fig. 4.

The window-casing is designated by the reference-letter a in theaccompanying drawings, while 1) indicates the blind or shutter.

The upper hinge for the blind may be of any well-known and suitablepattern. One member of the lower hinge consists of a plate 0, which maybe secured to the outer face of the casing by screws or as otherwisedesired and from which projects an integral arm d, having a cylindricalprojection e at its end, which receives the spindle f of the othermember-of the hinge, this member consisting of a plate g, carrying saidspindle at its free end and secured to the outside of the blind. Theupper end of the spindle f carries a bevelwheel h, which is rigidlysecured thereto in any desired manner. This bevel-wheel may also, ofcourse, be formed with the end of member 9 of the hinge, if desired, thespindle in this instance only projecting downwardly, of course.

'i is a shaft that is journaled in the windowcasing a, its outer endcarrying a bevel-wheel j, which meshes with the bevel-wheel h, and itsinner end protruding through the inner portion of the casing. In orderto provide efficient bearings for this shaft, metallic sleeves 70 may bemounted in the casing and receive said shaft.

If the bevel-wheel j is integrally formed upon the outer end of theshaft c', the plate 0 may be provided with an elongated vertical orificej for the reception of the shaft This slot affords a loose bearing forthe shaft, so as to facilitate the assembling of the parts.

receives the reduced flattened end Z of a T- shaped handle m, saidreduced-flattened end being hinged between the bifurcations of the shaftupon a pivot 71, that connects said bifurcations. It should be remarkedthat the surface of the body of the handle an is flush with the surfaceof the shaft when'the handle is in its extended position relativelyplate may be secured in position by' screws.

r designates an elongated plate -spring which is set in the slot 8,formed near the inher end of'the shaft i, said spring being secured inthe slot preferably by screws. The

outer surface of this spring lies flush with the surface of the shaftwhen at rest in the slot; but when its free end is appreciably liftedthe spring is raised out of the slot and immediately engages one of thenotches q in the plate.

The handle m is provided with a longitudinal rib t or other project-ion,which is adapted to engage one of the slots 13 when said handle is inits folded position-that is to say, in the position shown in thedrawings.

The plate-spring r is made long enough to project over the hinge formedbetween the handle and the shaft, and it is adapted to bear againsteither the free end edge of the former or upon the upper surface of itsfiattcned reduced end. In order, therefore, that the free end of thespring may lie flush with the surface of the shaft when the handle is inits extended position, the reduced flattened end of the latter is cutout, as at u, to receive the spring. In order to augment the action ofthe spring in maintaining the handle in its folded position, the freeedge of the flattened extension of the latter is inclined, its highestpoint being adjacent the outer edge of said flattened end.

It will be seen that in order to operate my improved shutter-worker itis only necessary, assuming that the handle is in its folded positionand engaging one of the slots in the disk, to turn said handle to itsextended position, where it can be most efficiently employed to rotatethe shaft i and consequently work the shutter or blind. \Vhen the blindhas been moved to the position desired, the

tent with the notches q to provide an imme diate securing means for theblind directly the latter has been moved to the position desired and thehandle turned in the slightest degree toward its extreme foldedposition. This arrangement renders the shu tter-worker a device that canbe used with the greatest facility where wind or some other force tendsto move the blind before the handle can be folded back to its permanentlocking position. Furthermore, it acts more or less to guide theprojectionitoward that slot in the plate which marks the positionoriginally selected for the blind to maintain.

In the modified form of the invention shown in Fig. 5 the free edge ofthe flattened reduced end of the handle, instead of being inclined, asshown in Fig. 4, is rounded, a cam edge, as at 1), being produced. Inthis instance the plate-spring r, constituting the detent, does notassume its position in the slot of the shaft when the handle takes itsfolded position, but it constantly engages a notch so long as the handleis not extended.

In order to protect the gearing which connects the shaft with the hingemember g, I have provided a box-like case w, having two of its adjacentsides removed. This case is shown in dotted lines in Fig. l and in fulllines in Fig. 2, and it is provided with ears 1 for receiving the screwswhereby the case is secured in position to the outside of thewindew-casing, one open side thereof being adjacent the hinge for theaccommodation of the bevel-wheel h and its adjacent parts and the otherbeing adjacent the face of the window casing for the accommodation ofthe shaft, its bevel-wheel, and the plate 0.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a window-casing, a blind, and a hingesustaining said blind on the casing, of a shaft journaled in said casingand projecting through the same, operative connection between said shaftand the movable member of the hinge, a handle pivotally connected to theinner end of the shaft and provided with a projection, said handle beingadapted to assume a position in longitudinal extension of the shaft or afolded position relatively thereto, a spring carried by the shaft andbearing against the handle to hold the latter in either of saidpositions and a radially-slotted disk secured to the inner face of thecasing, and adapted to be engaged by the projection of the handle whenthe latter is in its folded position, substantially as described.
